A programme for children at home.
Presenters this week, Marla Landi, Gordon Clyde

Although it may be cold outside, there are places indoors in parks and gardens where it is as warm as a summer's day, so that plants from other warmer lands may live through the cold winter.
'Mac' MacDonald of Kew Gardens will tell two stories this week about some of these interesting plants he looks after.
His story today is called "The plant that couldn't stop growing"
